To aZZ whom it may concern:

Be it known that I, DAVID G-ESSNER,Of Worcester, county of \Vorcester, State of Massa chusetts, have invented a new and useful Improvement in Cloth-Pressing Machines, of which the following is a specification.

The invention which is the subject of this application is an improvement on a machine similar to that described in Patent No.193,193, dated July 17, 1877, to Springborn and Baush, but preferably having two bed-plates, one above and the other below the cylinder, in lieu of the bed-plate and cylinder shown in said patent.

This invention consists in the provision of means whereby the cylinder and either bedplate can be adjusted relatively to one another, so that the cylinder and other bedplate can be operated while substantially no pressure is exerted by the first bed-plate.

In the drawing I have shown the arrangement of cylinder and bed-plates with reference to each other and to the bed of the machine and the method of sustaining theirjour- 11a s.

a is the frame of the machine, extending upward in the two branches 1) b.

c is the cylinder, which is journaled in the box d, which is adapted to slide up and down between the two branches of the frame. Below the cylinder the bed-plate e is supported in the frame. Above the cylinder is the second bed-plate, f, which is jonrnaled in the boxes 9 at 9. These boxes slide up and down between the branches of theframe above the boxes d. Suitable gearing (notshowm) is employed for turning the cylinder 0.

Pressure is exerted on the top of bed-plate f by a lever, 70, pivoted at one end to the frame and at the other connected by the rodt' to a weighted lever, as shown. This lever h is pivotally secured to ears j on the box 9, and it is also raised by the hand-lever it, which at one end acts on it as a cam.

Zis a stirrup on top of the box d, which is connected with the box 9 by a stud, m, depending from the box 9, and which passes loosely through a hole in the stirrup Z, and is provided with a nut, 19, at its lower end, so as to serve as a lifter. The nut on this stud m is so adjusted that the bedplate f may be lifted slightly before the cylinder begins to be lifted.

Between the box cl and the frame is interposed a set-screw, a, one at each end of the machine. These setscrews may be so adjusted as to remove the pressure from between the cylinder 0 and bed-plates e, or allow pressure to be exerted there. With one adjustment of the setscrew n the pressure which is applied to the upper bed-plate is transmitted through the cylinder to the lower bed-plate, and any goods passing through the machine are pressed both at the lower and upper bed-plates. Vith another adjustment of the set-screw a the pressure applied to the upper bed-plate is transmitted to the cylinder and from the sliding boxes, in which the cylinder is mounted, through the set-screw a to the frame, which serves as an adjustable rest. Under these circumstances no pressure is exerted on the goods by the lower bed-plate, but only by the upper one.

0 is a second nut on the stud Z. By the downward adjustment of this not the upper bedplate may be raised from the cylinder, so that when the pressure is brought to bear on the sliding boxes of the bed-plate, the pressure instead of being transmit-ted through the cloth to the cylinder,is transmitted through the stud m with its nut 0, which serves as an adjustable rest and stirrup, Z. Thus the cloth may be relieved of pressure between the cylinder and upper bed-plate while it is still being subjected to pressure between the cylinder and lower bed-plate. Thus by the adjustments of the nuts 0 or set-screws n the pressure may-be relieved from either bed-plate without effecting the operation of the other.

As the specific means for relieving the pressure between the cylinder and the b ed plate, I have shown the setscrew a and nut 0,- but it is obvious that other mechanical devices might be substituted for accomplishing the same result which would suggest themselves to a skilled mechanic and be practically equivalents of those shown.

The advantages ofthis improvement are that in case one bed-plate becomes damaged in any way or in case the pressure of only one bed plate is required the machine may be run with practically no pressure on either one of the bed-plates, while all the remaining parts perform their usual functions.
